To all whom it may concern:

B i vknowicl at ,1, L O lNor, a c t en f th R pu l c of Fr nc esi ing a La Ga nn filo m es, Seine, rance, av invented certain new and useful Improvements in vor Relating to Folding Spring Mattresses; and I dodeclare the following to be a full, clear, and exact description of the invention, such ass-will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a folding metallic springmattress of great strength and, owing to the small space it occupies when folded up, comparatively easy to carry, even yha d,

his mattress presents the following interesting features l. A framework composed of longitudinal members, between which hinged cross frames are maintained in a rigid position a by articulated obliq e stays, whilst lower cross frames, provided to take 111 a portion of the load, also help to keep the longitudinal frame members parallel.

2. A meshwork adapted to stretch laterally and composed of articulated strips of metal which lend themselves to the operation of folding and aresupported by a flexible framework made of bandsof metal stayed by conical springs which distribute the load of the surface. V

With reference to the accompanying drawings V Figure 1 is a plan of themattress viewed from above; I

Figure 2 is the plan viewed-from below;

Figure 8 shows the mattress partly folded, as a plan viewed from below; 1

Figure 4: is a longitudinal section along the line XX of Figure 1; I

Figure 5 is a cross section along the line Figure 6 shows on a larger scale, the articulationof the oblique stays, and

Figure 7 is a view, on a larger scale, of the articulation of the cross frames.

With reference to Figure-1, the jmattress comprises two 7 frame .members of channel section, 1 and 2, connected together by articulated angle-iron cross 'members, composed of two parts 3 and 1 pivoted at 5 and 6 and lhinged together by means of a plate 7 of the section indicated in Figure 7 so as to cover the central lower metal band 8, which, in conjunction with another band 9,

situated in the same plane, forms thestationary portion of the mattress. p

In order to impartthe desired rigidity to the mattress as a whole, use ismade, at the corners, of collapsible or folding stays 10,

articulated at 11 to the longitudinal frame '1 members 1 and 2, and at 12 to the parts 3 andt of the cross frame members.

v In addition, two struts 13 and 1d are articulated at 11 to the oblique stays, whilst their centre is in the form of a hinge 15 on which engages the end of a drawbar 16, articulated at the opposite end to the plate 7 forming the hinge of the parts 3 and 4: ofthe cross frame members. a

These struts 13 and M are for the pur-.

pose of sustaining the, central lower band 8 and intermediate lower bands 17, 18 which The foregoing description relates to theframework ofthemattress, which is completed by a special metallic meshwork supporting the bedclothes. This meshwork is formed of a plurality of small metallic strips 19, some of which are articulated to the longitudinalframe members 1 and 2, and others to the axial band'9 constituting a fixed portion ofthe mattress, In both cases these strips are also articulated to the upper intermediate bands 17 and 18 on ivots 19 engaging in slots 20.

Conical springs 21 are provided between two consecutive articulations 19 at a certain number of points along the bands and on the inner side thereof, said springsbeing suitably retained by means of caps 22 accommodating the fixing screws 23 and ensuring flexibility between the upper and lower bands, a

The intermediate bands 17 and 18 vare provided, at their ends,,with slots2-i into which fit bolts 25 secured to the corresponding parts 3 and 4t of the cross-frame members. These same intermediatebands are also provided with recesses, formed by brackets 26, in which the oblique stayslO are adapted to move freely during thevclosing movement, whilst the outer face of the same brackets acts as a seating from conical springs 21 situated at the ends, r

In accordance with the foregoing the folding of the mattress takes place in the follow:

ing manner: i

The mattress is turned upside down,as in Flgure 2, and the rigidity of the oblique stays 10 is destroyed by simple pressure of the joints in the desired direction, whilst at the same time a pull is exerted on the hinged parts of the cross frame members, towards the interior of the mattress, the effect of which is to push the drawbars 16, which destroy the rigidity of the struts 18 and 14 by the play of their joints 1115. The folding process is now started, and a slight pressure on the longitudinal frame members is sufficient to complete it. The mattress as described gives maximum elasticity by its aggregation of steel bands stayed by springs, ensures a proper distribution of the load on the surface, and, moreover, can be applied to any existing wooden or iron bedstead, provided there is suflicient seating for its use.

What I claim is 1. Folding metallic spring mattress characterized by the framework being composed of two parallel longitudinal frame members of channel iron connected by pivots to two perpendicular cross frame members articulated at the middle; oblique articulated stays maintaining rigidity at the corners; lower struts, articulated at the middle and ends,

ensuring the parallelism of the longitudinal frame members; a set of central bands forming the fixed portion of the mattress; intermediate bands, parallel with the first named, assisting to carry the load, conjointly with a meshwork of, metal strips and conical springs arranged between the bands.

2. A folding spring mattress comprising parallel longitudinal side bars, cross frame members pivotally connected to said side bars and articulated together, a centrally arranged bar connected to said cross frame members, struts pivotally connected to the side bars and to said centrally arranged bar, and draw bars connecting the articulations of the cross frame members and struts.

3. A folding spring mattress compris ing parallel longitudinal side bars, cross frame members pivotally connected to said side bars and articulated together, a centrally arranged bar connected to said cross frame members, struts pivotally connected to the side bars and to said centrally arranged bar, draw bars connecting the articulations of the cross frame members and struts, and plates covering the articulations of the cross frame members.

i l. A folding spring mattress comprising parallel longitudinal side bars, cross frame members pivotally connected to said side bars and articulated together, a centrally arranged bar connected to said cross frame members, struts pivotally connected to the side bars and to said centrally arranged bar, draw bars connecting the articulations of the cross frame members and struts, intermediate bars, and oblique stays, each comprising a pair of members pivotally connected together, one member of each stay being pivotally connected to a side bar and the other member being pivotally connected to a cross frame member and also slidably connected to an intermediate bar.

5. Folding metallic spring mattress char acterized by the framework being composed of two parallel longitudinal frame members of channel iron connected by pivots to two perpendicular cross frame members articulated at the middle; oblique articulated stays maintaining rigidity at the corners; lower struts, articulated at the middle and ends, ensuring the parallelism of the longitudinal frame members; a set of central bands forming the fixed portion of the mattress; intermediate bands, parallel with the first named, assisting to carry the load, conjointly with a meshwork of metal strips, conical springs arranged between the bands, and brackets attached to the inner faces of the intermediate bars and between which the oblique'stays are arranged to move.

6. Folding metallic spring mattress characterized by the framework being composed of two parallel longitudinal frame members of channel iron connected by pivots to two perpendicular cross frame members articulated at the middle; oblique articulated stays maintaining rigidity at the corners; lower struts, articulated at the middle and ends, ensuring the parallelism of the longitudinal frame members; a set of central bands forming the fixed portion of the mattress; intermediate bands, parallel with the first named, assisting to carry the load, conjointly with a meshwork of metal strips, a conical springs arranged between the bands, and strips pivotally connected to the side bars and central bar and slidably connected to the intermediate bars.
